Grand Prize – The Independence Day, by Marko Korošec, Julesburg, Colorado, US: "While on storm chasing expeditions in Tornado Alley, USA, I have encountered many photogenic supercell storms. This photograph was taken while we were approaching the storm near Julesburg, Colorado on 28 May 2013. The storm was tornado-warned for more than one hour, but stayed a low precipitation (LP) storm through all its cycles, and never produced a tornado: just occasional brief funnels, large hail and some rain."Marko Korošec/National Geographic Traveler Photo ContestSecond Place – First Time, by Agnieszka Traczewska, Mea Shearim, Jerusalem, Israel: "In Mea She'arim, an ultra-Orthodox district of Jerusalem, newly married Aaron and Rivkeh are to be together, for the very first time, alone. Their marriage was arranged by families. The 18-year-old couple confirmed the choice after only meeting once. Since then, until their wedding day, they were prohibited to meet or even talk."Agnieszka Traczewska/National Geographic Traveler Photo ContestThird Place – Diver in Magic Kingdom, by Marc Henauer, Grüner See at Tragöss, Austria: "Green Lake (Grüner See) is located in Tragöss, Austria. In spring snowmelt raises the lake's level about 10 meters. This phenomenon, which lasts only a few weeks, covers the hiking trails, meadows and trees. The result is a magical-to-see diving landscapes."Marc Henauer/National Geographic Traveler Photo ContestMerit – End of the World, by Sean Hacker Teper, Banos, Ecuador: "This photo, taken at the 'end of the world' swing in Banos, Ecuador, captures a man on the swing overlooking an erupting Mt Tungurahua.

Next up: the 2014 National Geographic Photo Contest, which was won by a photo of a woman spotlit by the glow of her phone on a crowded train. Selected from more than 9,000 entries, the photo, titled "A Node Glows In The Dark", was shot at Ocean Park in Hong Kong. The photographer, Brian Yen of Hong Kong, said: "I feel a certain contradiction when I look at the picture. On the one hand, I feel the liberating gift of technology. On the other hand, I feel people don't even try to be neighbourly anymore, because they don't have to."

Nicole Cambre of Brussels, Belgium, won in the nature category for a photo of migrating wildebeests in Tanzania.

Michael "Nick" Nichols of the US has been named Overall Wildlife Photographer of the Year 2014 for his photo, The Last Great Picture, depicting the five females of the Vumbi pride lying at rest with their cubs on a kopje (a rocky outcrop), in Tanzania's Serengeti.

He photographed them in infrared, which he says "cuts through the dust and haze, transforms the light and turns the moment into something primal, biblical almost". A few months later, he heard that the pride had ventured into land beyond the park and the three females had been killed.

Francisco Negroni of Chile won the Earth's Environments category with his image of volcanic lightning, entitled Apocalypse.

After the Puyehue-Cordón Caulle volcanic complex began erupting, Negroni travelled to Puyehue National Park in southern Chile. He watched as flashes of lightning lacerated the sky and the glow from the molten lava lit up the smoke billowing upwards and illuminated the landscape. "It was the most incredible thing I have seen in my life," he said.

Volcanic lightning (also known as a "dirty thunderstorm") is a rare, short‑lived phenomenon probably caused by the static electrical charges resulting from the crashing together of fragments of red‑hot rock, ash and vapour high in the volcanic plume.

Bruno D'Amicis of Italy won the World in our Hands category with his photo, called The Price They Pay.

A teenager from a village in southern Tunisia offers to sell a three-month-old fennec fox, one of a litter of pups he dug out of their den in the Sahara Desert.

Catching or killing wild fennec foxes is illegal in Tunisia but widespread, which D'Amicis discovered as part of a long-term project to investigate the issues facing endangered species in the Sahara.

Top prize in the British Wildlife Photography Awards went to Lee Acaster from Suffolk for his photo of a greylag goose by the Thames. Acaster said: "I was set up for shooting a stormy cityscape with a manual focus wide angle lens on when I came across the goose sat on the river wall. Expecting it to fly away as I got nearer, I was surprised to find that it was very happy to stay where it was, even when I got very close.

"It was technically incredibly difficult to get the shot, holding a flash out in one hand and my camera in the other, trying to focus on the goose by moving closer to him without scaring him away. I ended up being just a few inches away from him for the final image. He was still happily stood on the wall as I left, probably wondering what on earth the strange man with the flashing light had been doing."

John Stanmeyer won the World Press Photo of the Year 2013 competition with this photo of African migrants on the shore of Djibouti city at night, raising their phones in an attempt to capture an inexpensive signal from neighbouring Somalia — a tenuous link to relatives abroad. Jillian Edelstein, one of the judges, said: "It's a photo that is connected to so many other stories—it opens up discussions about technology, globalisation, migration, poverty, desperation, alienation, humanity. It's a very sophisticated, powerfully nuanced image. It is so subtly done, so poetic, yet instilled with meaning, conveying issues of great gravity and concern in the world today."
